To ALL WHoM 1r MAY coNeEnN:

Beit known that I, FRANCIS H. HOLTON, of Brooklyn, in the countyrof Kings, have invented certain new and useful Improvements in Nursing-Nipplesg'and Ido following is a full, clear, and exact description of the' same, reference being had to the making a portion of this specification, in which` Figure 1 is a longitudinal section of a nursing-nipple made according to my invention.

Figure 2 is a perspective view of the same.

Similar letters of reference indicate corresponding parts in both gures.

' T is invention consists in an India-rubber nursing-nipple having an annular stop-Haneh formed in one piece and State of New York, hereby declare that the accompanying drawings,

'nippleirom passing too far lnto the mouth ofthe infant The invention further consists in a novel means of attachmg the nipple to a suitable tube, the milk qr other liquid ispassedto the nipple.

To enable others to understand the nature and construction of my invention, with reference to the drawings.

A. represents a hollow or tubular nipple, of the usual or of any suitable form, and made of India rubber or equivalent material, the nipple being formed with an orifice, a, of any appropriate size, at its outer end, through which the milk o1' other liquid passing through the nipple may At the inner end of the nipple,

the innermost or central portion of which is made hollow, as shown in fig. l; the cavity thus provided internally in the anch communicating with the through which I will proceed to describeuijw is a tubular piece of wood, or other like material, the central portion, a,.of which is cylinthe interior of the pipe or tube C, to which it is designed to attach and has at one end a circumferential bead or enlargement, b, and at the other a broad flange or disk, c. In order to attach"the'nipple to the tube C, the opening -at'the ilanched or inner end of the nipple is elongated by stretching apart the two opposite edges of theanch, whereupon theilange or disk, c', of the piece B is inserted or passed into the cavity, formed as hereinbefore.setfortlu inthe interior of the lanch 6, and being thus brought into the position represented in fig. l, the piece-B is -securely attached to the nipple. The opposite end of the piece B is then inserted into the end ot' the't'ub'e C; and the annular bead being embedded, as it`were, in the inner surface of the. tube, secured to the latter, and serves to connect the nippletherewith, at the same time that the nipple should circumstances so require.

It is intended that the tube C should communicate with a bottle or other suitable vessel containing the milk or other liquid with which the infant is to be fed, such liquid being drawn through th'e apparatus in theY same manner as through an ordinary nipple, and the llanch 6 acting as a stop to prevent the nipple from passing too far into the mouth of the infant using the same..

What I claim as my invention, and desire to secure by Letters Patent, is

1. The India-rubber nipple, having the annularor circumferential stop-Hauch, constructed in one piece therewith, substantially as and for the purpose specified.

2. The hollow tlanch for attaching the nipple to the tube, tially as shown and described.
